FAC-System
FAC System is a mechanical construction set, invented by Swedish artist Mark Sylwan and launched in 1952. It uses metallic parts, and extensively uses steel rod. 100929 web.telia.com 100929 facsystem.se The company continued in business , supplying kits stated to give industry a basic construction system which gives the same freedom in 3D design as is available from the drawing board and CAD/CAM. Kits are suitable, and priced as, for laboratory work and teaching. Shafts have a diameter of 6 mm, and have a groove along the shaft. Gears or other wheels have a bevel on either side of the hub of the wheel. A special sheet metal angle fits into this chamfer, and when the wheel is mounted on an axle, this sheet metal angle will fit into the groove on the axle. The design allows the wheel to be fixed on the axle and the stop screws on the wheel only have the task of ensuring that the wheel does not move along the axle.

Construction Set
A construction set is a set of standardized pieces that allow for the construction of a variety of different models. The pieces avoid the lead-time of manufacturing custom pieces, and of requiring special training or design time to construct complex systems. This makes them suitable for temporary structures, or for use as children's toys. One very popular brand is Lego. Categories Construction sets can be categorized according to their connection method and geometry: * Struts of variable length that are connected to any point along another strut, and at nodes. ** Tesseract connection points are initially flexible but can be made rigid with the addition of clips. * Struts of fixed but multiple lengths that are connected by nodes are good for building space frames, and often have components that allow full rotational freedom. ** D8h (*228) nodes are used for K'Nex, Tinkertoys, Playskool Pipeworks, Cleversticks and interlocking disks in general. ** D6h nodes are used for ...

Drawing Board
A drawing board (also drawing table, drafting table or architect's table) is, in its antique form, a kind of multipurpose desk which can be used for any kind of drawing, writing or impromptu sketching on a large sheet of paper or for reading a large format book or other oversized document or for drafting precise technical illustrations (such as engineering drawings or architectural drawings). The drawing table used to be a frequent companion to a pedestal desk in a study or private library, during the pre-industrial and early industrial era. During the Industrial Revolution, draftsmanship gradually became a specialized trade and drawing tables slowly moved out of the libraries and offices of most gentlemen. They became more utilitarian and were built of steel and plastic instead of fine woods and brass. More recently, engineers and draftsmen use the drawing board for making and modifying drawings on paper with ink or pencil. Different drawing instruments ( set square, protrac ...

CAD/CAM
CAD/CAM refers to the integration of Computer-aided design (CAD) and Computer-aided manufacturing (CAM). Both of these require powerful computers. ''CAD'' software helps designers and draftsmen; ''CAM'' "reduces manpower costs" in the manufacturing process. Overview Both ''CAD'' and ''CAM'' are computer-intensive. Although, in 1981, Computervision was #1 and IBM was #2, IBM had a major advantage: its systems could accommodate "eight to 20" users at a time, whereas most competitors only had enough power to accommodate "four to six." ''CAD/CAM'' was described by ''The New York Times'' as a "computerized design and manufacturing process" that made its debut "when Computervision pioneered it in the 1970's." Other 1980s major players in ''CAD/CAM'' included General Electric and Parametric Technology Corporation; the latter subsequently acquired Computervision, which had been acquired by Prime Computer. CAD/CAM originated in the 1960s; an IBM 360/44 was used to build via ''CNC'' th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meccano
Meccano is a brand of model construction system created in 1898 by Frank Hornby in Liverpool, England. The system consists of reusable metal strips, plates, angle girders, wheels, axles and gears, and plastic parts that are connected using nuts and bolts. It enables the building of working models and mechanical devices. In 1913, a very similar construction set was introduced in the United States under the brand name Erector. In 2000, Meccano bought the Erector brand and unified its presence on all continents. In 2013, the Meccano brand was acquired by the Canadian toy company Spin Master. Meccano maintains a manufacturing facility in Calais, France. History First sets In 1901 Frank Hornby, a clerk from Liverpool, England, invented and patented a new toy called "Mechanics Made Easy" that was based on the principles of mechanical engineering. It was a model construction kit consisting of perforated metal strips, plates and girders, with wheels, pulleys, gears, shaft collar ...

Structural System
A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space. Load-bearing Buildings, aircraft, skeletons, anthills, beaver dams, bridges and salt domes are all examples of load-bearing structures. The results of construction are divided into buildings and non-building structures, and make up the infrastructure of a human society. Built structures are broadly divided by their varying design approaches and standards, into categories including building structures, ...
